New rider help

[Ridelikebrian]

Hi, I’m a new rider and having mechanical issues with my enduro 250cc but don’t know what. I’ll start by saying it’ was brand new buying it , and I’d ride it about 20-30 miles on it 5 days a week. After a couple months in, I was coming off a stop sign and switching gears was fine until I put it in 4th, then suddenly the bike started bogging down and sputtering. It would then die shortly after. Sometime I can get it to turn back on but if it does it shuts back off or won’t have full power when giving it gas. It has moments where it runs fine for a bit but will not stay well and 100% all day. It’s fuel injected so no carb. Oil was at good level and spark plug still good. There is this thing that looks like a sensor that broke, not sure if that’s related to the problem, I attached pics. And I don’t know what kind of sensor it is. Any help is appreciated . Thanks in advance! :
